Decentralized Platoon Join-in-Middle Protocol Considering Communication Delay for Connected and Automated Vehicle.

Cooperative driving is an essential component of intelligent transport systems (ITSs). It promises greater safety, reduced accidents, efficient traffic flow, and fuel consumption reduction. Vehicle platooning is a representative service model for ITS.

Extremely Low-Profile Monopolar Microstrip Antenna with Wide Bandwidth.

In this paper, we propose a new monopolar microstrip antenna for a high-speed moving swarm sensor network. The proposed antenna shows an extremely thin substrate thickness supported with an omni-directional radiation pattern and wide operation frequency bandwidth. First, to achieve the low-profile monopolar microstrip antenna, the symmetrical center feeding network and the gap-coupled six arrayed patches which form a hexagonal microstrip radiator were utilized.

Design of a Cooperative Lane Change Protocol for a Connected and Automated Vehicle Based on an Estimation of the Communication Delay.

Connected and automated vehicles (CAVs) have recently attracted a great deal of attention. Various studies have been conducted to improve vehicle and traffic safety through vehicle to vehicle (V2V) communication. In the field of CAVs, lane change research is considered a very challenging subject.

Influence of Surface Charges/Chemistry on the Catalysis of Perovskite Complexes.

The electrochemical performance of the perovskite complex was discovered to depend greatly on the different locations of the identical particle, which represent different surface charges accordingly. The surface charges were evaluated by Zeta potential (ζ) for the intrinsic BSCF5582 (BaSrCoFeO), ball-milled (BM-BSCF5582), and heat-treated in an oxygen atmosphere after ball-milling (48h-O-BM-BSCF5582), the mean ζ of which represents -11.1, 21.

Progressive Assessment on the Decomposition Reaction of Na Superionic Conducting Ceramics.

The successful analysis on the microstructure of Hong-type Na superionic conducting (NASICON) ceramics revealed that it consists of several heterogeneous phases: NASICON grains with rectangular shapes, monoclinic round ZrO particles, grain boundaries, a SiO-rich vitrified phase, Na-rich amorphous particles, and pores. A dramatic microstructural evolution of NASICON ceramics was demonstrated via an in situ analysis, which showed that NASICON grains sequentially lost their original morphology and were transformed into comminuted particles (as indicated by the immersion of bulk NASICON samples into seawater at a temperature of 80 °C). The consecutive X-ray diffraction analysis represented that the significant shear stress inside NASICON ceramics caused their structural decomposition, during which HO ions occupied ceramic Na sites (predominantly along the (1̅11) and (1̅33) planes), while the original Na cations came out in the (020) plane of the NASICON ceramic crystalline structure.

Short rare hTERT-VNTR2-2nd alleles are associated with prostate cancer susceptibility and influence gene expression.

Background: The hTERT (human telomerase reverse transcriptase) gene contains five variable number tandem repeats (VNTR) and previous studies have described polymorphisms for hTERT-VNTR2-2nd. We investigated how allelic variation in hTERT-VNTR2-2nd may affect susceptibility to prostate cancer.

Methods: A case-control study was performed using DNA from 421 cancer-free male controls and 329 patients with prostate cancer.
